COMBINED PLOW AND SOIL-PULVERIZING- IMPLEMET.-

Application ined Marcil 419, 192s. serieu No. 95,s33.`

l This invention includes a plow especially adapted to be Operated by a power tractor 'and having a. rotatable soil pulverizing de- Mvice mounted on a substantially vertical axis in a position to operatively 'engage theV freshly turned surface of thefurrow slice;

The pulverizing device is arranged to rotate in a direction to engage thefurrow slicejust as it leaves the rearward edge of the moldboard and to breakup and throw the soil into the furrow with the stubble and litter -in a coveredfconditiony at the bottom thereof.

A feature of the invention resides in the elimination of the rearward portion of the plow moldboard and the mounting of the soil pulverizer at the rearward. edge -thus provided and adjacent the plowed-land side of the furrow.

Another'feature of the invention resides `in the provision of a relatively small caster` wheel for operation in the furrow closely tormay'be applied to lift the plow out of adjacent the heel of the plow.

Still another featureofv the invention resides in the provision of a'power lifting device by means of which the pull of the tracthe ground.

Other features ofthe invention will be hereinafter referred to. v

In the drawings, in which a. preferred embodiment of ythe invention has been selected i 'for illustration: f

Figure 1, is a View in side elevation of a tractor-pulled .combination plow and soil pulverizer embodying the invention,- the tractor having a rear wheel removed for clearness of illustration.

Figure 2 is a plan View shown in "F igure 1.

Figure 3 isa view in Avertical section taken von the line 10.-'10 of Figure '1.

Referring to the drawings fora more de' tailed description of the invention, a plow l()` is coupled at the'forward end of the beam 11, to a hitch device 12 which in turn is at-A tached 'to the draw bar head 13,'of a tractor 14;. The rearward end of 'the plow beam 11,

is supported on a relatively small trailer or furrow wheel 15 which has a pivoted or caster support in the plow'beamat- 16.

. A feature of the invention re'sides in the mounting of a rotatable soil'. pulverizer 17, in a bracket 18 on the beam 11, the pulverl the rearward edge 19 of the of the devices izer being thus supported in a position at the plowed-land side of the furrow and adjacent It will be seen that the ordinary rearward extension of the plow moldboard is eliminated in order 'toaccommodate the pulverizer 17. l

Vith .the structural arrangement referred to, the pulverizer 17 rotates in a clockwise direction so that the blades 20 engage the freshly turned surface of the furrow slice just as it passes from the edge of the short moldboard of the plow 10, and throws the soil forwardly and outwardly into the furrow. This mannerI of engagement of the pulverizing blades with the rear orunderneath side of the furrow slice insures the covering' of stubble and litterby the pulverized. soil and produces a pulverized seed bed with stubble and litter turned underneath.

plow moldboard.

Another useful effect of themounting of f the pulverizer inthe position `shown isv the economical use of power which results. Itv

will be seen that the engagement of the soil in a direction vto throw it away from the moldboard, relievesl the moldboard of the friction of the material, a further saving of friction being effected bythe relatively short surface presented by the moldboard for the travel of the furrow slice therealonglv In addition to the economy of power thus effected, it has been found that the structure described will function with different soils which have heretofore been worked with plows of the disc type. Y

The function of the'plow share is to cut a furrow slice in the ordinary manner and the mold board is so lshapedl as vto simply lift the furrow slice to a nearly upright position and to perform the function of doing only the initial part of the turning over movement of the furrow slice. The pulverizer is placed so close to the mear end of the plow share that the entire furrow slice will be engaged by the pulverizer blades and thoroughly pulverized from a point near the llower edge of the furrow slice to the? upper portion thereof and the turning over movement completed before the' furrow slice can slide offl the mold board toward the previously turned furrow, when operating at. any plowing speed.

The pulverizer 17 is driven through a rotatable shaft 21, connected at its forward end 'series ofblades fixed to the shaft and art a power-takeoff device '22, carried by the the lower -edge of the furrow slice to the tractor and at its rearward end to an o'peratupper portion thereof.v v ing head 23, which supports the pulveriz'er 2.
